Troubleshooting with the Measurement & Automation Explorer (MAX)

MAX contains configuration information for all CAN hardware installed on the system. To start MAX, double-click on the Measurement & Automation icon on the desktop. Your NI-CAN cards are listed in the left pane (Configuration) under Devices and Interfaces.

You can test the NI-CAN cards by choosing Tools»NI-CAN»Test All Local Cards from the menu, or you can right-click on an NI-CAN card and choose Self Test. If the Self Test fails, refer to Troubleshooting Self Test Failures.

If there is no National Instruments CAN Interfaces item, and you have an NI-CAN card installed, refer to Missing NI-CAN or LIN Interface.

Missing NI-CAN or LIN Interface

If you have an NI-CAN card installed, but no NI-CAN card appears in the configuration section of MAX under Devices and Interfaces, you need to search for hardware changes by pressing the F5 key or choosing the Refresh option from the View menu in MAX.

If the NI-CAN card still doesn't show up, you may have a resource conflict in the Windows Device Manager. Refer to the documentation for the Windows operating system for instructions on how to resolve the problem using the Device Manager.
